So I've been slowly pulling cruise control parts off a 1987 244 for my 87 245. Looking at this diagram and reading others guides I seem to be missing the part that controls brake lights in a cruise control equipped car. I'm guessing inn yhe diagram it's part #5. Where is this located at in a 244 and what doesn't it look like?

 

part 5 on that diagram is a wire harness.

the brake light switch doesn't appear to be shown in that diagram, but it should be right up against the arm of the brake pedal such that when you step on the brake even a little bit, it releases the switch, which closes the brake light circuit (in other words, its a 'normally open' switch, pressing the switch closes the circuit).

 

Would that be part #9? It has a switch similar to what I've seen for brake lights and a vacuum port.

 

9 is a vacuum release that disables the cruise control when you step on the brake. its not an electric switch at all, and its independent of teh brake light switch. the vacuum release, and teh brake light switch are mounted right next to each other, both are depressed when the brake lever is at rest, all the way up, and are released when you depress the brake pedal even a little bit.
